本文通过差热分析（DTA）和X射线粉末衍射（XRD）方法研究了赝二元系LiF-CaAlF5的相平衡关系．该赝二元系在LiF：CaAlF5=1：1处形成一致融熔化合物LiCaAlF6，其熔点为814℃，并分别在LiF～LiCaAlF6和LiCaAlF6～CaAlF5区域形成两个共晶体系，其共晶温度分别为705℃和781℃．根据体系的相图，采用坩埚下降法生长出氟化物激光晶体Cr3＋：LiCaAlF6．

The effect of carbide solvation on the γ/γ+δ boundary temperature Tδ and the equilibrium relationship between the alloying elements at the γ/γy +δ boundary in austenitic steels at high temperature have been studied, and the variation of the ferrite volume fraction with temperature in α+ γ dual phase steel has been investigated. The relative expressions are derived from many experimental results, which provides a basis for quantitative calculation, composition design, determination of the working processes,and prediction of the mechanical properties and the structure of the austenitic steels.
